There's rarely any need to use the ampersand notation. I think you shouldn't use it unless necessary.
Some people feel more comfortable using &. It leads to less action at a distance (where perl parses differently depending on whether it's already seen a sub declaration). But if you do choose to use &, always use () with it.
